In my playbook, I run the gitlab-rake backup command works as expected. Now I want to print the output for this example its "1706574679_2024_01_29_16.4.5_gitlab_backup.tar" but I'm struggling to find a way on how to print this.
here's my playbook:
tasks:
- name: GitLab rake backup
become: yes
shell: "gitlab-backup create SKIP=repositories,db,uploads"
register: gitlab_backup
- debug: "msg={{gitlab_backup.stdout | regex_search ('Creating backup archive:'.'*') }}"
this is the output when the backup completed:

I only need to print this file name: 1706574679_2024_01_29_16.4.5
Anyone can help
I only need to print this file name in my stdout: 1706574679_2024_01_29_16.4.5
Anyone can help
solution 1:
- debug:
var: backup_name
vars:
backup_name: "{{ gitlab_backup.stdout | regex_search('Creating backup archive:\\s(.*?)\\s','\\1') | join('') }}"
here we use gitlab_backup which you are registering from your backup task and using regex we search for pattern and match just the part which is backup file name. and in the end we join the values. here join is used to just convert output of regex_search to string since output type is list.
solution 2: if You are not good with regex(which regex in solution 1 is really simple) you can use this one. it feels more like filtering with tr/grep/cut in shell:
- debug:
var: bak_name
vars:
bak_name: "{{ gitlab_backup.stdout_lines | select('match', '.*Creating backup archive.*done') | join('') | split(' ') | select('match','^\\d+_.*') }}"
grep)tr ' ' '\n')grep '^[0-9]*_')
